In sum, although it is reasonable to assume that the activities of an enzyme on alternative (metabolically available) substrates may often depend on neutral drift, the point is difficult to prove because various types of selective pressures can be at play, and these will be different in different or

2020-04-13
Enzyme selectivity of many Fmoc-Thr(tBu)-OH like β-galactosidases, acylases, epoxyhydrolases, lipases, etc. has also been modulated by using different immobilization techniques. It can result in the selection of optimal biocatalyst for different processes. This has many advantages over strategies l

The enantiomeric ratio (ER) of chiral compounds accumulated in organisms has been found to be different among species (Borga and Bidleman, 2005, Harner et al., 1999, Warner et al., 2005, Wiberg et al., 2000), indicating enantioselective accumulation of chiral compounds are species-specific. The ER o

In addition to EGFR, other receptor tyrosine kinases (RTKs) also play roles in the tumor progression under hypoxia, especially hepatocyte growth factor receptor (cMet) (Le et al., 2012). Our data suggested that unlike EGFR, hypoxia had no apparent effect on cMet E-64-c synthesis (data not shown), su

First of all, two assumptions just as in Ref. [30] are need to simplify the penetration process: (1) The crater phases is short and the as 481 synthesis of EFP is consumed little; thus, the influence of crater on penetration can be ignored; (2) the initial stagnation radial pressure is equal to axi

The P4H activity and the large number of 4-Hyp residues that are formed, amounting to half of all the Pro residues or 10% of all residues, have been identified as having a clear role in the structure and chemistry of the triple helix [3]. The role of the rare 3-Hyp residues is less clear and is stil

Gamboge is a dry resin obtained from Garcinia hanburyi HOOK. f. (Guttiferae). It has a variety of bioactivities, including detoxifying, homeostasis maintaining, anti-inflammatory and parasiticidic effects. Available evidence suggests that gamboge bears anticancer characteristics with gambogenic casp

Inflammatory action of certain cytokines can influence cell proliferative routes (Deshmane et al., 2009). When mTOR is inhibited, for instance by the action of Rapa, TGF-β1, which has an anti-inflammatory action, is increased. The relationship between high levels of TGF-β1 and cystamine arrest has

As temperatures increase, rates of spontaneous deamination also increase such that hyperthermophilic organisms must have efficient mechanisms for dealing with this potential hazard.8., 9. The hyperthermophile Methanococcus jannaschii has both a dCTP deaminase (encoded by the gene at locus MJ0430) an

The genetic basis of resistance to dieldrin has been described for several insect species as a mutation in the transmembrane domain II of the GABA-Cl or rdl (resistance to dieldrin) gene (ffrench-Constant et al., 2004; Bass et al., 2004; Du et al., 2005). A mutation in the GABA-Cl gene was found at

Are the hydrogens removed simultaneously or one by one? — Δ1-KSTDs can catalyze the exchange of alkali-labile tritium or deuterium atoms at the C2 N6-Methyl-dATP of their substrates, even when enzyme turnover was prevented by the absence of an electron acceptor for the oxidative half-reaction [97,98
